Hierbei nehmen die Amminkomplexe eine bedeutende Stellung ein. Zwischen dem Hexaamminchrom(III)-ion [Cr(NH<sub>3</sub>)<sub>6</sub>]<sup>3+</sup> und dem reinen Aquakomplex [Cr(H<sub>2</sub>O)<sub>6</sub>]<sup>3+</sup> gibt es mehrere Übergänge vom Aquapentaamminchrom(III)- bis zum Tetraaquadiamminchrom(III)-ion. Daneben existieren eine Reihe von gemischten Amminkomplexen mit organischen Liganden, wie z.&#160;B. <a href="/wiki/Ethylendiamin" title="Ethylendiamin">Ethylendiamin</a>. Komplexe vom Typ [CrX<sub>6</sub>]<sup>3−</sup> existieren mit den Liganden <a href="/wiki/Fluorid" class="mw-redirect" title="Fluorid">Fluoride</a>, <a href="/wiki/Chlorid" class="mw-redirect" title="Chlorid">Chloride</a>, <a href="/wiki/Thiocyanat" class="mw-redirect" title="Thiocyanat">Thiocyanate</a> und <a href="/wiki/Cyanid" class="mw-redirect" title="Cyanid">Cyanide</a>. Auch hier gibt es mehrere gemischte Formen. Ein Beispiel ist das <a href="/wiki/Reinecke-Salz" title="Reinecke-Salz">Reinecke-Salz</a> NH<sub>4</sub>[Cr(SCN)<sub>4</sub>(NH<sub>3</sub>)<sub>2</sub>], das in der <a href="/wiki/Analytische_Chemie" title="Analytische Chemie">analytischen Chemie</a> zum Fällen von <a href="/wiki/Kation" title="Kation">Kationen</a> eine Rolle spielt. Gemischte Aquachlorokomplexe treten in <a href="/wiki/Chrom(III)-chlorid" title="Chrom(III)-chlorid">Chrom(III)-chloridlösungen</a> auf und haben den Begriff <a href="/wiki/Isomerie#Konstitutionsisomerie_von_Komplexverbindungen" title="Isomerie">Hydratationsisomerie</a> geprägt. Aquasulfatokomplexe können sich in <a href="/wiki/Chrom(III)-sulfat" title="Chrom(III)-sulfat">Chrom(III)-sulfatlösungen</a> bilden. Mehrkernige Komplexe bilden sich bevorzugt über Oxo- bzw. Hydroxobrücken, z.&#160;B. [(NH<sub>3</sub>)<sub>5</sub>Cr(OH)Cr(NH<sub>3</sub>)<sub>5</sub>]<sup>5+</sup>. Komplexe mit anderen Oxidationsstufen des Chroms sind zum Teil unbeständig. Verbindungen von Chrom(II) sind starke Reduktionsmittel. Hier sind beispielsweise Amminkomplexe, wie das [Cr(NH<sub>3</sub>)<sub>6</sub>]<sup>2+</sup>, Komplexe mit <a href="/wiki/Hydrazin" title="Hydrazin">Hydrazin</a>, Ethylendiamin, <a href="/wiki/Bipyridine" title="Bipyridine">Bipyridine</a> und dem Thiocyanation bekannt.
